Abstract
Abstract
A series of novel multiblock polyethers, (PEOm-PPOn)k, were synthesized via the anionic polymerization using ethylene glycol as the initiated core. Respectively, they were named as E340, E540 and E740, due to the block number (3, 5, 7) and the content of ethylene oxide (EO, 40 w%), which were confirmed by the Fourier transform infrared (FT-IR), 1H NMR, and GPC. Moreover, their bulk properties were determined as pseudoplastic fluid by the rotational rheometer. It was found that their solubility and surface tension were all gradually weakened with the addition of block numbers. Nevertheless, the dynamic modulus tended contrary trends. As confirmed to thier microemulsion performance, it was more easier to be destroyed the hydrophilic-lipophilic balance for the E740. Herein, the E740 could be potentially used as micro-emulsion demulsification and wastewater treatment.
